I have a vaio control center but can not find viao care to activate internal scans

I have owned this computer for about a year and am only now getting comfortable with it. I was lucky enough to buy it used from a renta place because they felt it was to expensive to rent out and cover repairs. I probubly paid more than I should but still tthought it a better deal and easier fit for my budget .In my eyes viao is the best. I want to use every option available to keep this running top notch and there are a few issues I need to address. I also bought a tashiba laptop for my husband and within only a couple months both computers had the dvd drives stop working. They run but are not recognised. I took them back to the company but all they did was reboot the origional system. I would like ton scan the drives and see if there is a way to get them running. I dont have any warrenties so if I can work it out all the better any help[ out there advise is welcome.
